...differing opinions?
Liberals, more accurately, Democrats are a dysfunctional party proven most recently by their ineffectiveness to pass legislation while holding a large majority from '09-'11-- At least other than that watered down gift to the Insurance Industry known as 'Obamacare' that couldn't even include the Public Option because of a lack of cohesiveness in their own party.
I'm telling you. If you want cohesiveness and a clear plan of attack, be a Republican.
The Democrats are too inclusive and are paying for it in all areas. They can't even protest effectively anymore because they include those who feel it necessary to call themselves Liberal, while defecating on a cop car-- when in actuality they are better suited to be called a delinquent or an anarchist.

The Democrats either open themselves up to providing haven for the delinquents and anarchists, or they don't mind being guilty by association.
Do you agree that it would be better for the Liberals to be shutoff to differing opinion, if only it were true. The Democratic Party has become a blob of inclusiveness with no real backbone and no real order.
What is your opinion?

Yep, you guys have a mind set of a rock, and just one person, Grover , and if you don't to his line, you are out. On the democrats side we have a coalition of ideas, and talk them over to come up with the best solutions. Not like you guys,one person controls the whole repub party.
